This deliverable presents the updated use case scenarios and requirement analysis of the AI-PRISM system design. It includes the description of the five different use cases of the AI-PRISM project and the related key performance indicators (KPIs). Furthermore, the deliverable contains the set of hierarchical requirements for subsequent system development: the high-level requirements identified so far by the stakeholders, and the system requirements (related to Hardware, Human Robot Collaboration aspects, the AI Enhancing Tools and the Social Collaboration aspects) resulting from the analysis of the stakeholder requirements. In addition, the requirement analysis also includes a mapping between the pilot requirements and the responsible technical components. This deliverable extends and updates D1.2 with respect to the use case descriptions and the KPIs. The use cases descriptions give a thorough overview of the current situations and the envisioned collaborative scenarios. Details about a Technology Pull / Technology Push methodology that supported the refinement of the use case definitions and the mapping of stakeholder requirements to system requirements is also given. Additionally, the key human factors dealt in each use case are also described in detail.
